An electronic device associated with a rotational casing includes a panel with a mount groove being joined to the rotational casing. An upper ILD layer is formed over the lower ILD layer, and a via and upper line structure are defined within the upper ILD layer. With the technical solution described herein, microblog accounts of products are displayed preferentially, the utilization rate of the microblog is thus enhanced. The product slides down the dispensing ramp and is stopped by a stop positioned adjacent the dispensing aperture. These attributes include, for example, aromatic vapor density, insecticide vapor density, ambient light intensity, ionic air content, ultrasonic frequency intensity, and the like. A temperature sensor in which sets of conductors and one or more temperature sensors are arranged inside a sheath and with respect to each other such that the conductors are provided closer to the center of the sheath than the temperature sensors.
